check if using tcps part II

in your current session, as written there, check sys_context('USERENV', 'NETWORK_PROTOCOL')

in another session, you could grab some hints out of the network service banner. Do the maths, when it is not-not using ssl, it probably is…

select sid,program,
case when program not like 'ora___@% (P%)' then
(select max(case
when NETWORK_SERVICE_BANNER like '%TCP/IP%'
then 'TCP'
when NETWORK_SERVICE_BANNER like '%Bequeath%'
then 'BEQUEATH'
when NETWORK_SERVICE_BANNER like '%IPC%'
then 'IPC'
when NETWORK_SERVICE_BANNER like '%SDP%'
then 'SDP'
when NETWORK_SERVICE_BANNER like '%NAMED P%'
then 'Named pipe'
when NETWORK_SERVICE_BANNER is null
then 'TCPS' end)
from V$SESSION_CONNECT_INFO i
where i.sid=s.sid) end protocol
from v$session s;
